In the poem 'My Parents' by Stephen Spender, how is the theme of social inequality conveyed?

There is no hiding the fact that there is a noticeable
break between who Spender's parents wanted him playing with and who they  did not (in
the poem "My Parents Kept Me From Children Who Were
Rough").

From the very beginning line, a reader can tell
that stereotypes were a great part of deciding who Stephen could play with. It seems
that Spender's parents found problems with anyone who fit the following
descriptions:

-Children who were
rough

-Children who spoke inappropriately and without
filtering or concern

- Children who worn torn
clothing

It seems that Stephen's parents found children
like this to be social outcasts whom belonged to lower class families (most cued by the
description of torn clothing).

Therefore, the theme of
social inequality is conveyed through the negative connotations assigned to the children
Stephen was not allowed to play with. In this, one could assume that Stephen did not
wear torn clothing, did not use offensive language, and did not play/act
rough.

This shows the reader that only those who did not do
these things were considered good enough for Stephen to associate with. By setting up
negatives, Spender automatically shows the opposite side through inference and
assumptions based upon the reader's knowledge of social
stereotypes.
